Definitions

  • the housing has at least two through bores or slots open at one end and which are perpendicular to the two oppositely facing boundary surfaces for receiving mounting screws.
  • the invention relates to a housing for a gear, for example a worm gear, spur wheel gear, bevel wheel gear, as used for connecting the shaft of a driving motor or engine to the input shaft of the appliance to be driven, with simultaneous speed reduction, or change in the position or direction of the drive axis.
  • a gear for example a worm gear, spur wheel gear, bevel wheel gear
  • a gear housing of substantially prismatic shape having six boundary planes, each perpendicular to its neighbors, and having recesses on two oppositely situated boundary planes, which recesses are bounded at the edges of the respective plane by flange-like projecting edge parts, wherein the flange-like projecting edge parts are formed with slots open at one end, for the introduction of fixing screws, and wherein the housing has at least two through bores or slots open at one end, which are perpendicular to the two said boundary planes situated opposite to each other.
  • the first-mentioned slots for the provision of the fixing screws permit fixing in the four planes connecting together the two mutually opposite boundary planes.
  • the through bores permit fixing of the gear housing to the two mutually opposite boundary planes provided with the recesses. It is advantageous for the slots, open at one end, are conically widened on the inside of the flange-like edge parts for the insertion of countersunk screwsfThe heads of the countersunk screws may be placed in these conically widened parts and nuts screwed on the other end of the screws.
  • the gear housing according to the invention may consist of a box-like part with cover set thereon, or also of a single, hollow casting, production being thereby rendered particularly simple and cheap.
  • the gear housing 1 is cast in one piece and has a number of openings 2, 3 for the insertion of gear parts and bearings. Furthermore, it has inspection openings 5 for inspection of its oil level or ice degree of wear of the gear, and finally, on some edges with oblique axis it has openings 6, 7 for the replenishment or discharge of lubricant or for venting in the event of heating of the gear.
  • the housing has a prismatic shape with six boundary planes 8, 8', 9, 9' and 10, 10', perpendicular to each other. The arrangements permitting the fixing of the housing in all these six planes are as follows:
  • recesses 12 are provided, which are closed by flange-like projecting edge parts 13 from the edges of the said principal boundary planes.
  • Slots 14, 15, open at one end, are provided in the said flanges, the said slots serving for the introduction of screw bolts, the screw heads bearing against the inside of the flanges 13.
  • the slots 15 are conically widened inwardly, so that the heads of the countersunk screws may be inserted in these widened portions without projecting inwardly.
  • such a gear housing may be fixed on each of the boundary planes by direct screwing to an adjacent component, whether to a motor or engine flange or to the housing of an appliance to be driven or also to a second like gear for achieving double transmission in the simplest way. It is thus possible for a single form of gear housing to solve all fixing problems.
  • a gear housing of substantially prismatic shape having six boundary planes, each perpendicular to its neighbors, and having recesses on two oppositely situated boundary planes, which recesses are bounded at the edges of the respective planes by flange-like projecting edge parts, wherein the flange-like projecting edge parts are formed with slots, open at one end, for the introduction of fixing screws, and wherein the housing has at least two through openings the longitudinal directions of which are perpendicular to the two said boundary planes situated opposite to each other.
  • a gear housing according to claim 1 wherein the slots are widened conically on the inside of the flange-like edge parts to accommodate the head of countersunk screws.
